66 ASSEMBLY – Pascal CHAMP / Cegelec
LMJ VACUUM VESSEL
Main steps• Factory pre-fabrication of boilerwork sub-assemblies for the chamber (shaping, machining, welding):
- 140 T of Aluminium (AW 5083)- 12 sectors - 100 mm thick- 2 caps - between 100 and 120 mm thick-203 crossbeams of between 200 and 1950 mm in diameter
• Final assembly of the chamber in a dedicated on-site workshop (machining, welding, testing)
• Handling of the assembled chamber (10 metres in diameter, 110 tonnes) - moving it into the LMJ test room - setting on its pedestal at 12 metres high.
• Installation of the concrete biological shielding. (400 mm – 220 T)
( Global Leakage rate : 10-6 Pa.m3/s - Degazing rate < 2.10-6 Pa.m/s after 4h )

CONCLUSION
Cegelec’s vision of Key success factors
• Integrated team with a mix design – manufacturing – site works at each stages from early design to integration
• Developments and tests done early before site works ateach stage – allows anticipation and correction of troubles
• Constant questioning : toolings, process modifications, ….
• Keep flexibility to manage interfaces evolutions
• Proper Management of various technologies, in-house or external expertise - Networking
